IMPROVEMENT IN CLAMPS FOR HOLDING BOLTS FROM TURNING.

Specification forming part of Letters Patent No. 206,954, dated August13, 1878; application filed June 4, 1878.

To all whom it may concern Be it known that I, JOHN W. LEETE, of SouthMeriden, in the State of Connecticut, have invented certain new anduseful Improvements in Devices for Holding Bolts from Turning when theirnuts are being loosened or tightened, which improvements are fullydescribed in the specification and accompanying drawings, in which--Figure 1 represents a perspective View of the device. Fig. 2 is a planview of the same, and illustrating the manner of its application. Fig. 3is a plan view, showing a modification; and Fig. 4 is a sectionalelevation of the device, illustrating its operation with a bolt.

The object of my invention is to furnish a device by which bolts may beprevented from turning with the nut when it is being loosened ortightened on the bolt.

In the drawings, A A and A represent a claw having in the upper end ofthe portion A the socket to. B is an adjustable bar working in saidsocket, and held in the same at any point by set-screw 1) working in oneof the sides of said socket and against the said bar. To the lower endof said adjustable bar is made the screw-threaded sleeve or eye 0.Working in said screw-threaded sleeve is the screw-shaft D, providedwith a wheelhandle, E, or its equivalent, a cross or lever handle, asmay be selected. The pressing end 0 of the screw-shaft is made pointedor taperin g toward a point, as shown in Fig. 3, when used foropcratin gwith countersink head-bolts, while for operating with button-head boltsthe pressing end may be made flattened or concave, as shown in Fig. 2.

In operating with my improved device with tire-bolts, the operatorplaces the claw A A A in position, as shown in Figs. 2, 3, and 4, withthe hook portions engaging with the inner side of the felly of thewheel. The screw-shaft is then adjusted so as to bring the bearing end 0of said screw-shaft directly opposite the head of the bolt. This is doneby sliding the bar B in or out, when the screw-shaft is to be revolvedand tightened endwise against the head of said bolt. WVhen the bolt tobe held is in a situation in which the head will not be central betweenthe hook of the claw, the bar B is to be turned in its socket to untilthe pressingpoint of the screw-shaft is brought opposite to the same, asin Fig. 2, and then set by setscrew 1), and the pressing-bar is then tobe tightened.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

1. In a device for holding bolts from turning, the combination, with theclaw A A A and screw-threaded shaft D, working in socket O, of the adjustable bar B, adapted to be raised or lowered to carry the saidscrew-shaft nigher to or farther from the portion A of said claw,substantially as and for the purpose set forth.

2. In a device for holding bolts from turning, the combination, with theclaw A A A and screw-shaft D,working in socket C, of the bar B,adaptedto be turned in either direction to carry the said screw-shaft at anyangle with said claw, substantially as and for the purpose set forth.
